To all whom it may concern f Be it known that I, NORVELL R. WYA'H, a'citi'zen of the'United States, residing at Gr'andview, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Non- Refillable Bottles, of a specification.

This invention relates to non-refillable bottles the primary object of which is to positively preclude reuse of the bottle unlessfthe neck, or at least a portion thereof has been severed from the bottle, preventing the selling of a spurious liquid under the same name as that of the original manufacture, or analogous fraudulent reuses.

Another object is to provide a compare- ,tively inexpensive bottle which although preventing refilling, will permit of the expeditious dispensing of the contents of the Other objects as well as the nature, characteristic features and scope of my invention will be more readily understood from the following description taken in connection with the accompanying drawings and pointed out in the claim forming a part of this specification.

Referring to the drawings :-.-Figure 1 is a longitudinal sectional view of a bottle neck constructed in accordance with my invention showing the stopper mountedtherein; Fig. 2 is a cross sectional view taken on the line 22 of Fig. 1; Fig. 3 is a perspective View of the stopper, and Fig. (1 is an elevational view of the valve chamber.

In the drawings wherein is illustrated the preferred embodiment of this invention a portion of a bottle body 5 is provided which.

has issuing therefrom a bottle neck 6, the latter in the present instance having its inner terminal constricted as indicated at 7 and provided adjacent its'outer endwith diametrically opposite depressions 8 to provide parallel recesses, the outer end of the bottle being provided withthe usual bead.

Mounted in the neck 6 is astopper 9 which in the present instance is preferably of a cylindrical configuration and has formed on its outer periphery a plurality of equidistant longitudinally extending ribs 10 so as to providefluid-ways 11, said ribs 10 being extended below the lower end of the stopper whereby communication is had With the interior of the stopper. Enlarged ribs 12 are formed on opposite sides of the stopwhich the following Specification of Letters Patent. Pgmpnt gd DQG. 141 1199115, Application its m 122, 191i. Serial in. 840,262. r

per 9 and are provided with elongated slots or recesses 13 which register with the entlv appearing.

Mounted in the bottle neck 6 is a valve chamber 15 in the present instance comprising a conical base 16 which has mounted thereon a rubber sleeve 17, said sleeve engaging with the constricted portion 7 of the bottle neck, the base 16 having a tubular portion 18 extending upwardly therefrom, being of a diameter relatively smaller than the upper end of said base, the portion 18 provided in its upper margin with a plurality of recesses 19 which communicate with the Ways 11 of the stopper 9. The lower inner periphery of the base 16 is enlarged and inclined as indicated at 20 to provlde a valve seat, it being thus far seen that communication is open through the valve chamber 15 and the stopper 14 so as to permit of the free dispensing of the contents of the bottle.

Mounted for movement in the valve chamber 15 is a ball valve 21 which is normally held in engagement with the valve seat 20 by an elastic element 22 the latter in the present instance comprising a coil spring. The convolution on one end of said spring is in engagement with the inner face of the enlarged portion 14 of the stopper 9 while the opposite end is in engagement with a guide sleeve 23, saidsleeve having a plurality of arms 24 extending therefrom. The outer terminals of said arms are slidably engaged with the inner periphery of the chamber 15 to prevent lateral thrust of the spring 22 and positively seat the valve 21 on its base. Refilling of the bottle is thereby prevented but'at the same time expeditious dispensing of the contents of the bottle is permitted, since by merely inverting the latter it is seen that the pressure on the interior of the bottle will be suflicient to overcome the resistance of the elastic element 22 in the neck 6, flat springs 25 are provided which are folded and engaged in the openings or recesses 13 of the stopper 9 so that neck the springs will automatically expand mto the recesses 8 in the bottle neck when the springs reach this point.

In operation, to dispense the contents of the bottle, the latter is inverted permitting the valve 21 to be unseated by pressure of the liquid on the interior of the bottle. Communication is thereby opened through the valve chamber 15 permitting the liquid to flow through the V-shaped openings 19 and through the openings in the bottom of the stopper 9, which are provided by extending the ribs 10, the liquid subsequently issuing through theways 11. It is seen that refilling of the bottle is positively prevented since even should the bottle be laid on its side and placed in a receptacle of Water or the like, which is frequently done in order to refill bottles, the valve 21will remain intact since it is necessary that the bottle be inverted in view of the fact that the contents of the bottle must be such as to overcome the resistance of the spring 22 for opening communication. It is likewise obvious that the insertion of wires or the like for unseating the valve is positively prevented in view of the peculiar formation of stopper and valve chamber.

It will be understood that the above description and accompanying drawings comprehend only the general and preferred embodiment of my invention and that various minor changes in details of construction, Eroportion and arrangement of parts, may

e made within the scope of the appended claim and without sacrificing any of the advantages of my invention.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:-

In combination with a bottle having a neck issuing therefrom, a means for preventing the refilling of said bottle including a chamber snugly engaged with the inner periphery of said neck and provided with an opening therein, the diameter of the lower end of which gradually decreases, a valve mounted for movement in said opening to close communication through the latter, said valve being unseated by the pressure of the liquid on the interior of the bottle when the latter is inverted, a spring to normally hold said valve in a closed position adjacent the lower terminal of said opening, a stopper mounted in said neck and abutting the outer end of said spring to prevent displacement of the latter, said stopper likewise preventing the introduction of means into said neck for unseating said valve.

' In testimony whereof I afiix my signature in presence of two witnesses.
